Title: Innovations of Stephen F Rounds

Introduction

Stephen F Rounds is an accomplished inventor based in San Clemente, California. He has made significant contributions to the field of navigation systems, holding a total of three patents. His work focuses on enhancing the accuracy and efficiency of navigation data generation for mobile objects.

Latest Patents

One of his latest patents is the RTK vector phase locked loop architecture. This innovative navigation system generates navigation data for mobile objects based on satellite navigation signals received from multiple satellites and base data from a stationary base station. The system computes position, velocity, and time estimates for the mobile object, utilizing code phase estimates and carrier phase estimates. It employs a Vector Delay Locked Loop (VDLL) computation process to generate code phase estimates and a RTK Vector Phase Locked Loop computation process for carrier phase estimates.

Another notable patent involves a navigation apparatus and method that models measurement quantization errors as states. This apparatus determines the estimated position of an object by receiving navigation information that includes a sequence of quantized measurements. Each measurement has a corresponding quantization error that is negatively correlated with the prior measurement's error. The apparatus iteratively performs a navigation update operation, determining a state and covariance matrix for the object using a Kalman filter update operation.
